01

What is it about?

24XX collects the rules behind the 2400 series into a document intended for adaptation. Although that series focuses on science fiction, the framework welcomes other settings. Jason Tocci supplies text, layout files, and a compatibility logo, supporting both play and the creation of attributed derivative publications.

02

At the table

Describe the situation and risk first, roll the appropriate dice, and keep the highest. Adapt the compact framework to the genre of your own game.
